Anonymous users2024-02-08In fact, there is no need to be so diligent, whether the engine is clean or not mainly depends on the engine oil, the oil is of high quality and has few impurities. I have always used imported German GT Magic Red, the quality of this PAO engine oil is much better than that of fully synthetic, basically there are no impurities, the cleanliness is good, I only do it once for almost 50,000 or 60,000 kilometers, and the engine is no problem at all.

Anonymous users2024-02-07Cars are already a must-have tool for everyone to get around. Of course, automotive knowledge is essential. In order to make it easier for everyone to understand this knowledge, today Bian Xiao will introduce to you the problem of whether the oil of the car is clean.
Interested friends can learn about it, it may be helpful to you.
The oil absorption of the car engine replacement is quite clean, and the residual old oil inside the engine must be minimized. If too much old oil is left in the engine, it will contaminate the new oil added and may reduce the lubrication performance of the new oil. Engine oil is very important to the engine, and has the role of lubrication, heat dissipation, cleaning, and sealing of the engine.
Engine oil can be said to be the blood of the engine. If you don't change the oil for a long time, a lot of sludge can be generated inside the engine. Moreover, the lubrication performance of the engine oil will be reduced if the engine is not changed for a long time, which may be related to the abnormal wear of the engine.
The four elements of oil selection:1. The oil should be selected according to the requirements of the engine.
It is not necessary to use an over-grade oil on a less demanding engine, nor on a more demanding engine. 2.Multigrade oils should be selected to the maximum.
Because of its economy, long life and high efficiency, multi-grade oil has a good guarantee effect on the engine. Due to the characteristics of the multi-grade oil, it is normal for the oil to darken prematurely and the oil pressure is lower than that of the oil oil. 3.
The quality of some domestic famous brand engine oil is very good, and it is much lower than that of similar imported products. There is no need to worry about using it, and there is no need to blindly pursue "foreign oil". 4.
If the engine is in good condition and the temperature is low in season, try to use a low-viscosity oil to keep the oil path unblocked. For example, during the hot season or when engine wear is severe, the use of a high viscosity oil will help to form an oil film and reduce engine wear.

Anonymous users2024-02-06If you need it, when you change the oil, buy a bottle of engine cleaner and add it, idle it for a few minutes, then let go of the old engine oil, and then add new engine oil. Otherwise, residual oil will reduce the effectiveness of synthetic oil.
Engine oil, that is, engine lubricant, English name: engine oil. The density is about to lubricate and reduce friction, assist cooling and cooling, seal leakage, rust and corrosion, shock absorption and cushioning for the engine. It is known as the blood of the car.
Engine oil is made up of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of imitation sail trap lubricating oil, and additives can make up for and improve the shortcomings of base oil performance, give some new properties, and are an important part of lubricating oil. The engine is the heart of the car, and there are many metal surfaces in the engine that are ready for friction and movement, and these parts move fast and in poor environments, and can operate at temperatures of 400°C to 600°C.
The new technology transforms natural gas into crystal-pure, fully synthetic base oils, on which is added with unique powered cleaning technology to create lubricants with superior cleaning protection. Under such harsh working conditions, only qualified lubricating oil can reduce the wear of engine parts and prolong the service life. (Photo by photo:.)

Anonymous users2024-02-05Summary. This is not serious, if it is clumped, it must be a state of hot car, and then go to change the oil, just wait for the oil temperature to rise, you will replace it, it will be put relatively clean, of course, if it is really dirty or something like this, you can also do this cleaning.
Should I clean the engine before changing the oil of the car engine? For example, using the engine to clean the oil.
Hello, happy to answer your questions.
Hello. Hello, this is not a must, under normal circumstances, if you change the oil according to the interval of kilometers, there is no need to make it clear.
But it's a little clumpy.
Is this a serious problem.
This is not serious, if it is clumped, it must be a state of hot car, and then go to change the oil, just wait for the oil temperature to rise, you will replace it, it will be put relatively clean, of course, if it is really dirty or something like this, you can also do this cleaning.
1. Is the cleaning agent harmful to the engine?
Long-term and high-speed operation of the engine during the addition of cleaning agent will cause wear and tear on the engine, but as long as the cleaning technician follows the cleaning process, there will be absolutely no long-term and high-speed operation. >>>More
Hello, it is generally divided into two cases:
1. If the engine does not leak oil, and there is only dust and dust on the surface, then it is okay not to clean, and there is no harm to the engine. >>>More
Generally, if it is a new car, there is no need to clean and maintain, only need to replace the oil normally, because the cleaning agent has a certain corrosiveness, it is easy to destroy the oil lubricating oil film, and it is not suitable for frequent use, it is recommended that the new car be cleaned after 50,000 kilometers. >>>More
If the carbon deposit is not cleaned for a long time, it will cause the operation of the whole vehicle, so that the internal channel of the engine will be blocked by carbon deposits, thereby reducing the power of the automobile engine, and the carbon deposits and deposits will block the needle valve and valve hole of the fuel injector, resulting in the intake valve not being closed tightly, and the cylinder pressure will drop or even temper, resulting in the engine fuel injection is not smooth, the idle speed is unstable, the power becomes poor, the fuel consumption increases and the exhaust emission deteriorates, and the combustion rate is too low. Carbon deposits on the piston top and cylinder head can easily cause local overheating of the combustion chamber and gasoline preheating, resulting in engine knocking and other failures. These failures can shorten the life of the engine. >>>More
The engine anti-wear protector has a certain effect, but it is only temporary, and the good protective agent is more expensive, and the engine oil is proportioned, and the random addition of additives may change the nature of the engine oil and affect the engine state. Therefore, it is best to change to a higher grade of engine oil, the original engine oil maintenance is now replaced with a fully synthetic engine oil such as Jin Mobil, and the original use of fully synthetic engine oil is now replaced by PAO GT engine oil, which will go to a higher level in power and quietness.
